摘　　要：美国高级加密标准(AES)作为全球通用的加密算法,目前已被广泛研究和使用。鉴于AES的重要性,计算机科学与技术、通信工程、电子信息工程、信息对抗技术等专业的高年级本科生或研究生的选修课中通常将AES加密算法作为一个重要内容列入教学计划。针对这些专业学生的特点和该算法的特殊性(如学生数学基础薄弱、算法内容抽象、课时少等情况),笔者研究了AES的教学思路,包括算法背景、算法分解、算法演示、算法攻击进展等教学要点,并结合教学经验加以分析讨论。At present,Senior U.S.encryption standard（AES） as a universal encryption algorithm has been widely studied and used.In view of the importance of AES,the AES encryption algorithm that will be elective courses of senior undergraduate or graduate student had make teaching plan in course such as Computer science and technology,the communication engineering,electronic and information engineering,information confront technology.According to the characteristics of these students and the particularity of the algorithm（such as students＇ mathematical foundation weak,the algorithm content abstract,little class hour etc）,combined with the teaching experience,the AES teaching ideas that included algorithm background,Algorithm decomposition,algorithm demo,algorithm attack,were researched and discussed.
